Description

Technical Field

[0001] The invention belongs to the technical field of asphalt concrete pavement construction management and relates to an asphalt concrete pavement construction quality detection and analysis method. Background Art

[0002] As one of the common pavement structures in road construction, asphalt concrete pavement is widely used in urban roads, highways, airport runways and other projects due to its good durability and bearing capacity. However, with the continuous increase in road traffic demand and the increasing vehicle load, higher requirements are placed on the quality of asphalt concrete pavement. Therefore, it is particularly important to detect and analyze the construction quality of asphalt concrete pavement.

[0003] However, the existing asphalt concrete pavement construction quality inspection technology still has certain limitations. Specifically, although the existing asphalt concrete pavement construction quality inspection technology has covered multiple inspection dimensions such as physical properties and structural performance inspection, surface properties and safety inspection, it ignores the detailed consideration of various engineering joints of the pavement and cannot provide strong support for the high-quality construction and maintenance of the pavement.

[0004] On the one hand, the lack of consideration of various types of engineering joints makes the road construction quality inspection results lack of detail. Different types of joints have different positions, functions and performance requirements in the road surface. For example, transverse joints and longitudinal joints mainly affect the flatness and integrity of the road surface, expansion joints and contraction joints are related to the stability of the road surface under temperature changes, and settlement joints play a key role in the road surface's adaptation to uneven foundation settlement. Existing technologies fail to include various types of engineering joints in the inspection process, resulting in the inability to accurately grasp the quality status of the road surface in various details, making it difficult to discover potential problems and hidden dangers.

[0005] On the other hand, the lack of consideration of various engineering joints also makes the road construction quality inspection results unreliable. During the use of the road, the joints are often prone to diseases, such as cracks, misalignment, water seepage, etc. Ignoring the importance of engineering joint quality in construction quality inspection may lead to more serious road damage in the subsequent use of asphalt concrete pavement, affecting the service life and driving safety of the road.

[0009] S3. Various types of simulated vehicles equipped with vehicle-mounted vibration devices and wheel force sensing devices are placed on the target road surface in turn for driving experiments, and the driving performance data of various types of simulated vehicles are recorded to analyze the basic driving quality evaluation indicators of the target road surface.

According to the positions and lengths of each expansion joint and each contraction joint of the target road surface, plan each expansion joint position block and each contraction joint position block of the target road surface and conduct corresponding temperature adaptability tests, so as to analyze the environmental adaptability quality evaluation index of the target road surface.

[0011] S5. Comprehensively consider the corresponding evaluation indicators of the target road surface’s basic construction quality, basic driving quality, and environmental adaptability quality, calculate the target road surface’s construction quality inspection score, and provide feedback.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) The present invention helps to have a more comprehensive understanding of the overall flatness and density of the road surface by planning each transverse joint area, each longitudinal joint area and each conventional area and detecting their corresponding flatness and density respectively, so as to accurately evaluate the basic construction quality of the target road surface.

[0014] (3) The present invention helps to understand the expansion joint environmental tolerance and contraction joint environmental tolerance of the target road surface by performing corresponding temperature adaptability tests on each expansion joint position plate and each contraction joint position plate of the target road surface, thereby evaluating the environmental adaptability quality of the target road surface and providing strong support for ensuring the quality and performance of asphalt concrete pavement.

[0015] (4) The present invention not only helps provide a more comprehensive and objective construction quality inspection score for the target road surface by comprehensively considering the corresponding evaluation indicators of the target road surface's basic construction quality, basic driving quality, and environmental adaptability quality, but also has strong practicality and environmental adaptability, providing strong support for road construction and maintenance.
